The ACM construction is suited to sealing applications that require stable performance in driveline environments, while the dust lip adds an extra barrier at the shaft interface. If you are replacing a leaking differential seal on a Mercedes-Benz, Honda Civic, or other vehicle using this OE-style size and profile, this part number 268.420 provides the dimensional match needed for service work.\u003c\/p\u003e\u003cp\u003eThis part cross-references Mercedes-Benz 020 997 19 47 and 023 997 90 47 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDifferential fluid seepage at the shaft seal area\u003c\/li\u003e\n\u003cli\u003eContamination entering the axle or differential housing\u003c\/li\u003e\n\u003cli\u003eNoise or wear caused by low lubricant level from a leaking seal\u003c\/li\u003e\n\u003cli\u003eSeal hardening, cracking, or lip wear from age and heat\u003c\/li\u003e\n\u003cli\u003eService replacement during driveline or axle maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the shaft diameter, housing bore, and seal height before installation. Clean the sealing surface thoroughly and inspect the shaft for grooves or corrosion that can shorten seal life. Use proper installation tools to seat the seal evenly and avoid damaging the dust lip or sealing edge.
